Duality and o − O-structure in non reflexive Banach spaces
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2020 Let E be a Banach space with a supremum type norm induced by a collection of functionals ℒ ⊂ X* where X is a reflexive Banach space.

Large BMO spaces vs interpolation [PDF]
Analysis & PDE, 2015 In this paper we introduce a class of BMO spaces which interpolate with $L_p$ and are sufficiently large to serve as endpoints for new singular integral operators. More precisely, let $( , , )$ be a $ $-finite measure space. Consider two filtrations of $ $ by successive refinement of two atomic $ $-algebras $ _\mathrm{a}, _\mathrm{b}$ having

Estimates for the commutators of operator Vα∇(−Δ+V)−β $V^{\alpha }\nabla (-\Delta +V)^{-\beta }$
Journal of Inequalities and Applications, 2019 Let a function b belong to the space BMOθ(ρ) $\operatorname{BMO}_{\theta }(\rho )$, which is larger than the space BMO(Rn) $\operatorname{BMO}(\mathbb{R}^{n})$, and let a nonnegative potential V belong to the reverse Hölder class RHs $\mathit{RH}_{s ...

Advection Dispersion Equation and BMO Space
Journal of Applied Mathematics and Physics, 2013 In this paper, we provide a new way of characterizing the upper and lower bound for the concentration and the gradient of concentration in advection dispersion equation under the condition that source term, concentration and stirring term belong to BMO space.

Stability and boundedness of regular solutions for a Sisko flow in an infinite annular porous space
Results in Physics, 2023 The present article is intended to study the boundedness of solutions for an unsteady non-Newtonian flow, whose strain–stress relationship is provided by the Sisko fluid model.

Parabolic BMO and global integrability of supersolutions to doubly nonlinear parabolic equations [PDF]
, 2015 We prove that local and global parabolic BMO spaces are equal thus extending the classical result of Reimann and Rychener. Moreover, we show that functions in parabolic BMO are exponentially integrable in a general class of space-time cylinders.

Estimates for the Commutators of p-Adic Hausdorff Operator on Herz-Morrey Spaces
Mathematics, 2019 In this paper, we investigate the boundedness of commutators of matrix Hausdorff operator on the weighted p-adic Herz-Morrey space with the symbol functions in weighted central bounded mean oscillations (BMO) and Lipschitz spaces.
